**Problem**
Some of the docs indicate --table can take a filename as an argument.
It didn't work for me, even though sending the contents of the file to stdin
and omitting --table did work:
<terminal>
# dmsetup create recover-vgbarley-home --readonly --table /root/recover-
vgbarley-home.dm
Invalid format on line 1 of table .
Command failed.
# dmsetup create recover-vgbarley-home --readonly < /root/recover-vgbarley-
home.dm
# ls /dev/mapper/reco*
/dev/mapper/recover-vgbarley-home
</terminal>
**Documentation**
The man page and dmsetup --help both indicate `--table table|table_file` as the
syntax. However, the man page further down says
--table table
Specify a one-line table directly on the command line. See below for
more information on the table format.
i.e., it gives no indication that a filename would be acceptable, or how
the program decides which interpretation to make of the argument. The
example above specified the file as a full absolute path in an unsuccessful
effort to trigger the correct interpretation.
The man also doesn't say whether the argument to --table needs to be quoted,
though I assume it does.
The description of the table format further down does not say what syntax
for "device" is acceptable, i.e., major:minor, full path, path relative to
/dev.
